SAMUEL WOODHEAD, OF WEST TROY, NEW YORK.

MACHINE FOR SEAMING SHEET-METAL ROOFS.

SPECIFICATION forming part of Letters Patent No. 259,786, dated June 20, 1882,

Application filed May 15, 188-2. (No model.)

To all whom it may concern;

Be it known that I, SAMUEL WOODHEAD, a citizen of the United States, residing at West Troy, Albany county, State of New York, have invented new and useful Improvements in Machines for Beaming Metal Roofs, of which the following is a specification.

, My invention relates to certain new and usefulimprovementsin machines for closing seams in sheet-metal roofs preparatory to soldering down the same, and more particularly to the machine shown and described in Letters Patent No. 233,828, granted tome October 6,1880, to which I refer for a full understanding of the same.

The object of my present invention is to simplify and perfect the construction of the patented machine; and with these ends in view my invention consists in the peculiar construction and arrangement of parts hereinafterfully described and specifically claimed.

In the construction shown in the patent above referred to, the seam-closin g wheels are journaled directly to the weight which constitutes the body of the machine, which weight is necessarily to be supported by the axle and handle when the machine is being transported as well as when in actual use, and the removal of the wheels for adjustment is only accomplished after turning the machine on its back,

as will be understood by reference to said patout. In my present machinethese difficulties are all overcome and many advantagesnot existing in the patented machine are acquired.

To enable those skilled to fully understand my invention, I will proceed to describe the same in detail, referring by letters to the accompanying drawings, in which-- Figure 1 is a top or plan view of a machine embodying my invention. Fig. 2 is a side elevation of the same, the dotted lines showing the position of the machine when in use; and Fig. 3 is a longitudinal vertical section taken at the line a: a: of Fig.1, and with the handle thrown back into the position necessary to lift the seaming-wheels for the purpose of removal or adjustment. f

Similar lettersindicate like parts in the several figures.

A A represent the side frames or body of the machine, to which the axle B is secured in any suitable manner. These frames are separated, as shown, so as to receive between them the handle 0 and weight-roller D. The han-- tile is pivotally connected to the axle, as clearly seen at Fig. 3, and the weighted roller is provided with short trunnious a or (seen in the dotted lines, Fig. 1) and collars b. The trunnions have their hearings in the rear ends of their frames A A and rotate freely therein.

E E are the seaming-rolls, arranged upon the axle B, the dotted lines seen at d (1 representing adj usting-collars, which are placed between the rolls and the frame of the machine, as illustrated, or between the wheels and the linch= pins when the wheels are placed against the body of the machine, to decrease the distance between them. The object of such adjustment is fully described in my Letters Patent hereinbefore referred to.

The handle 0 is provided with a rear extension, F, of a length slightly greater than the height of the axle B from the ground, so that when the handle is thrown rearward, as shown at Fig. 3, the axle B serving as a fulcrum, the rolls E E will be lifted and readily removed or adj usted. The handle, when in this position, is supported, as clearly seen, by contact with the weighted roll D. The extension F of the handle is formed with lateral wings or projections, (seen in dotted lines 0 6, Fig. 1,) which are adapted to come in contact with and bear against shoulders ff on the inside of frames A A, (see Figs. 1 and 2,) so that when the forward end of the handle 0 is depressed, as

seen in dotted lines, Fig. 2, the weighted roller D and frames A A will be lifted, the axle B serving as a fulcrum, and in this way the strength of the operator and the Weight of V the roller D combine to produce the necessary pressure of the seaming-rolls E E upon the seam to be closed.

The handle 0 may be so applied to the axle as to be readily removable therefrom, and the .roller D, instead of being framed with the trunnious and collars, as shown, may be secured in place bya removable axle passing through the same and the frames AA, and thus be adapted for removal fromthe machine.

It will be observed that the roller 1) serves as a combined support, with therolls E E, for

the frame of. the machine when the same is being transported from point to point on the roof, and is not a dead-weight, as is the casein the machine forming the subject of my patent referred to.

What I claim as new, and desire to secure by Letters Patent, is-

1. I11 combination with the seaming-rollersE E and axle B, the side frames, A, and weighted roller D, adapted to belifted or vibrated upon the axle B, substantially as and for the purpose set forth.

2. In combination with the rolls E, frames A, and weighted roller D, the handle 0, pivoted to the axle and formed with the extension F, adapted to support the rolls E in an elevated position, as and for the purpose set forth.

3. The side frames, A, formed with the r 5 In testimony whereof I have hereunto set 20 my hand and seal in the presence of two subscribing witnesses.
